. BINDER FOR LEAVES SPECIFICATION forming part of Letters Patent No.484,275, dated October 11, 1892.

Application filed March 31, 1892. Serial No. 427.242. (No model.)

To on whom it may concern.-

Be it known that I, GEORGE H. WmsLow, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements.

in Binders for Leaves, of which improvements the following is aspecification.

The invention described herein relates to certain improvements in meansfor temporarily'securing loose leaves together, and has forits object aconstruction whereby the leaves may be easily and securely fastenedtogether for use in the same manner as the leaves of a book and readilyremoved when desired.

In general terms, the invention consists in the construction andcombination substantially as hereinafter more fully described andspecifically claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a perspective View of one end of my improved binder. Figs.2, 3, and 4 are perspective views of the turning-plate, thelocking-piece, and prong, respectively. Fig. 5 is a plan View of thebinder, showing the position of the parts for inserting the leaves..Fig. 6 is a side elevation of the same, showing the manner of securingthe binder to the back of the inclosing boards. Fig. 7 is a perspectiveview of a modified form of the binder. I Fig. Sis aplan View of anotherform. Fig. 9 is a bottom plan of the construction shown in Fig. 8, andFig. 10 is a transverse section of the same.

In the practice of my invention the back or foundation plate 1 is madeof a strip of metal, of a width proportional to the combined thicknessof the largest number of leaves which it may be desirable to bindtogether and of length a little greater than that of the leaves. Theends of this strip are T-shaped and are turned up and the arms of the Tbent around to form a guard or protector 2 for the ends of the leaves.Swinging plates 3 are pivoted on the plate 1one near each endthereof-and on opposite edges of the plates are formed side pieces 4,which preferably extend from the ends of the plates toward the middlethereof, the distance between the innor ends of the side pieces beingapproximately equal to the combined thickness of the leaves to be bound.To these side pieces pieces, and by turning the combined prong and guarda quarter of a revolution into the position shown in Fig. l the feet 8pass under the sidepieces from opposite sides, portions of the plate 3being cut away, so as to permit the passage of the feet under the sidepiece, thereby locking the prong and guard to the side pieces, the prongprojecting at right angles to the side pieces, and the guard lying onand parallel therewith.

As shown in Figs. 1 and 2, the side pieces are slightly benttransversely, so as to form shoulders at on both sides thereof, saidshoulders preventing the longitudinal movement of the prong and guard,so that the legs pass on opposite sides thereof, as shown.

\Vhen it is desired to apply the binder, the swinging plates 3 areturned, as shown in Fig. 5, at right angles to the back or foundationplate 1. The leaves, having suitable holes punched therein for thereception of the prongs 5, are then placed parallel with the back platebetween the inner ends of the side pieces 4, as indicated by dottedlines in Fig. 5. The swinging plates are then turned around parallelwith the back plate, thereby forcing the prongs through the leaves,which are held as against lateral movement by the stops 9. The stops areformed on the back plate 1 and are so located as to be alongside of theprongs, or approximately so, when the latter are in normal position. Itwill be observed that the stops 9 not only serve to hold the leaveswhile pressing the prongs through them, but also serve to prevent theleaves from slipping olf the prongs. If desired, the ends of the prongsmay be pointed, so that they will pass through the leaves, forming theirown holes therethrough;

In order to provide an additional security as against the slipping offof the leaves, arms 10, provided with heads 11, are so pivoted to theside pieces that when turned down to the position shown in Figs. 1 and 6the heads 11 will bear against the leaves on the side of the prongsopposite the stops 9. It will be observed by reference to Figs. 1 and 6that the heads 11 are so constructed that when the heads are turned downtheir upper edges will form practically a continuation of the upperedges of the guards 6 and stops 9. The heads 11 are provided withprojections 12, which pass through slots 13 and 14 in the swinging andback plates when the former is turned to normal position, as shown inFigs. 1 and 6, thereby lockin g the swinging plate as against accidentaldisplacement. When it is desired to turn the plate 3 into the positionshown in Fig. 5, the pivoted lock 11 is turned back until the arm 10 isat right angles to the upper edge of the side piece 4. It will beobserved that when the head 11 is turned down to the position shown inFigs. 1 and 6 it closes the gap between the inner ends of the sidepieces, and will therefore by reason of its bearing against the leavesheld in the binder prevent any turning of the plate 3, so that, ifdesired, the projection 12 in the head may be omitted.

In order to attach the binder between suitable covers, loops 15 areattached to the under side of the back plate for the reception of a tape16, attached to the covers. If desired, supports 17 for the leaves maybe formed on the back or foundation plate between the swinging plates 3,and said supports may be slotted for tapes to secure the binder betweencovers, as shown in Fig. 6.

In Fig 7 the guards and prongs 5 are shown integral with the side pieces4 of the swinging plates. The locks for holding the leaves on the prongsconsist of arms 18, pivotally mounted on the swinging plates and adaptedto be turned up alongside of the leaves and holding the same on theprongs. N otches 19 are formed in the ends of the prongs into which thearms spring, thereby holding the latter in looking position. Theoperation of this form of binder is similar to that described inconnection with the construction shown in Figs. 1 to 6.

In Figs. 8 to 10 is illustrated a further modification of myimprovement, wherein the movable plate 3 is made in two sections orparts, consisting of angular pieces of metal having the prongs 5attached to their vertical sides 4, and the horizontal side adapted toslide one over the other when inserting or removing the prongs. Theplates are held toagainst accidental displacement.

ing the spring so that when its longest diameter is in line with thelugs the plates may be separated the desired distance and the leavesplaced in position. Then by turning the spring the plates will be drawntogether.

It is characteristic of the several forms or modifications shown anddescribed herein and of other forms which would readily suggestthemselves to the skilled mechanic without departing from the spirit ofmy invention that the prongs are inserted and removed from the leaves bya lateral movement of the movable plate.

It will readily be understood that as the prongs 5 on the plate projectinward from the opposite edge of the plate and overlap the leaves willbe held onto the prongs by the side pieces, if the plate 3 be looked asagainst lateral movement with reference to the leaves.

- I claim herein as my invention-- 1. A binder for leaves, consisting ofa laterally-movable plate provided with side pieces havinginwardly-projecting prongs attached thereto and adapted to be pushedthrough the leaves bya lateral movement of the plate, substantially asset forth.

2. A binder for leaves, having, in combination, a base or foundationplate, a plate movably -connected thereto and provided with side pieceshaving inwardly-projectin g prongs attached thereto, substantially asset forth.

3. A binder for leaves, having, in combination, a movable plate providedwith side pieces having inwardly-projecting prongs attached thereto anda lock for holding the leaves upon the prongs, substantially as setforth.

4. A binder for leaves, having, in combination, a base or foundationplate, a plate pivoted thereon and provided with vertical sides onopposite edges, and prongs detachably connected to said sides,substantially as set forth.

5. A binder for leaves, having, in combination, a base or foundationplate provided with guards along its edges, a plate pivotally mounted onthe base-plate and provided with vertical sides, inwardly-projectingprongs attached to the sides, and locks for holding the leaves on theprongs and locking the movable plate parallel with the base-plate,substantially as set forth.

6. In a binder for leaves, the combination of a base or foundationplate, a plate movably connected to the base or foundation plate andprovided with side pieces having inwardly-projecting prongs, and alocking device for holding the movable plate parallel with thebase-plate, substantially as set forth.

In testimony whereof I have hereunto set my hand.
